Description

technical field

[0001] The invention relates to the technical field of photovoltaic power generation, in particular to a monitoring system for photovoltaic power generation units. Background technique

[0002] The rapid development of my country's photovoltaic industry has played a positive role in increasing my country's energy supply, adjusting energy structure and protecting the ecological environment. Due to the influence of special meteorological factors, photovoltaic projects are mostly located in places with relatively harsh natural conditions such as the northwest and coastal areas, and power generation The distribution of the stations is relatively scattered, and the office management site is far away from the equipment site, generally at least a few kilometers away. The long-distance office has caused inconvenience to equipment management and operation.

[0003] In the photovoltaic field, each photovoltaic array will be equipped with a box-type transformer, two inve...
